THE EFFECT OF USING NANO TITANIUM AS A PARTIAL REPLACEMENT OF CEMENT ON THE MECHANICAL PROPERTIES AND PHOTOCATALYTIC PROPERTIES OF MORTAR

Abstract

This research aims to study the effect of adding Nano titanium (TiO2) on the mechanical properties and photocatalytic properties of cement mortar. To achieve these goals, three different percentages of Nano TiO2 were investigated 2%, 3%, and 4% by Wt. of cement. Compressive strength, Flexural strength, and Splitting strength were measured. Different method of dispersing Nano TiO2 were investigated to reach the optimum utilization of Nano materials. In addition, the effect of adding Nano TiO2 on the photocatalytic properties of cement mortar was investigated. The study showed that Nano TiO2 has a significant effect on the photocatalytic process, which gives the mortar new properties in the process of self-cleaning.
